The current userptr page population will defer work to a work item if needed to avoid ever taking the mmap_sem in the direct call path. With the more fine-grained locking in etnaviv this isn't needed anymore, so a future commit will simplify this code. Add a lockdep annotation to validate the assumption that the mmap_sem can be taken in the direct call path.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
